Abstract

The utility model relates to computer technology and can be used as part of computer equipment, monoblocks, small desktop computers and embedded systems. The technical result is to increase the range of domestic components used in the system board. The device is made using the domestic BE-M1000 central processor. The use of a control and monitoring controller as part of the device, made on the domestic controller K1986 BE1QI, allows you to increase the range of domestic components used.

Description

The utility model relates to computer technology and can be used as part of computer technology, monoblocks, small desktop computers and embedded systems.

As part of the implementation of the import substitution program, it is very important to increase the share of used domestic electronic components in the development and modernization of electronic computing facilities. To this end, it is necessary to increase the range of used domestic components, including central processors, microcontrollers that have the necessary set of external and internal interfaces to implement the functions required from computing equipment. It is also very important to ensure the safety of both the computing equipment itself and the tasks that are solved with its use.

Currently, most computing equipment, including monoblocks, small desktop computers and embedded systems, are developed using motherboards that have similar characteristics, but are completely made on imported electronic components. Examples of such motherboards include:

ASUS H110I-PLUS;

ASUS PRIME A320I-K / CSM;

Gigabyte GA-IMBLAP3350;

Gigabyte GA-IMB1900N.

The lack of these motherboards is the use of imported microcircuits as a central processor.

Known motherboard E107 in the mini-ITX form factor manufactured by EDELWEISS LLC (https://edelweiss-tech.ru/product/komplektuyushchie-edelveys/platy-edelveys/sistemnaya-plata-e107/).

The well-known motherboard is based on the domestic BE-M1000 processor from Baikal Electronics and has the following main characteristics:

central processor - BE-M1000 by Baikal Electronics;

RAM - 2 DDR4 channels;

expansion slots - M.2 with E (A) key (PCIe x1 + USB2.0), PCIe x8;

video - HDMI;

USB - two USB 3.0 ports and two USB 2.0 ports;

data drives - two SATA ports, four Mini-SAS HD SFF-8643;

network - two 10 Gigabit 10GBase-T (SFP +) ports, four 1 Gigabit Ethernet 1000Base-T (RJ-45) ports;

fan control system;

indication and control - LEDs, buttons;

remote control and monitoring - BMC ASPEEED AST2500.

The disadvantages of the well-known motherboard are the use of the imported AST2500 controller for control and monitoring, the lack of the ability to connect the Trusted Platform Module (TPM), and the absence of a chassis intrusion sensor. These disadvantages reduce the safety of both the computing equipment itself, which uses the known motherboard, and those tasks that are solved with its use. And the use of an imported controller reduces the range of used domestic components.

Another motherboard TF307 is known in the mini-ITX form factor manufactured by EDELWEISS LLC (https://edelweiss-tech.ru/product/komplektuyushchie-edelveys/platy-edelveys/plata-na-baykal-m/).

The well-known motherboard TF307 is based on the domestic BE-M1000 processor from Baikal Electronics and has the following main characteristics:

central processor - BE-M1000 by Baikal Electronics;

RAM - 2 DDR4 channels;

expansion slots - M.2 with M key (PCIe x4), PCIe x8;

video - HDMI, LVDS;

USB - two USB 3.0 ports and four USB 2.0 ports;

data storage devices - two SATA ports;

network - two ports 1 Gigabit Ethernet 1000Base-T (RJ-45);

audio - audio line-out, audio line-in, microphone-in;

fan control system;

indication and control - LEDs, buttons;

control and monitoring - STM32 series controller.

The disadvantages of the well-known motherboard TF307 are the use of an imported STM32 series controller for control and monitoring, the lack of the ability to connect a Trusted Platform Module (TPM), and the absence of a chassis intrusion sensor. These disadvantages reduce the safety of both the computing equipment itself, which uses the known motherboard, and those tasks that are solved with its use. And the use of an imported controller reduces the range of used domestic components.

The technical result achieved by the claimed utility model consists in increasing the range of used domestic components in the motherboard.

The specified technical result is achieved by using a motherboard that includes the domestic central processor BE-M1000 from Baikal Electronics, with a re-programmable read-only memory (EPROM) connected to it via the SPI interface; two channels of DDR4 RAM; real time clock; M.2 expansion slot with M key connected to the CPU via PCIe x4 interface for connecting external solid-state drives SSD; M.2 slot with E key, connected to the central processor via PCIe x4, USB2.0, SDIO, I ² C interfaces for connecting modules such as Wi-Fi, Bluetooth; two SATA connectors for connecting external hard drives; two four-channel USB3.0 hubs with 4 USB3.0 connectors connected to them; PCIe bus switch, switching the PCIe bus either to the PCIe x8 slot, or to the PCIe to USB3.1 bus converter, two USB Type C connectors with support for the power delivery PD function are connected to the PCIe bus converter; two microcircuits of the physical layer 1 Gigabit Ethernet 1000Base-T with 1 Gigabit Ethernet 1000Base-T RJ-45 connectors connected to them; two-channel 10G-KR / KX4 to 10GBase-R interface converter with two 10Gigabit Ethernet 10GBase-R connectors connected to it for connecting optical SFP + modules; one LVDS connector; HDMI connector for connecting a monitor; audio amplifier with line-out, line-in and microphone-in connectors connected to it; fan control system connected via SMBus to the central processor; UART to USB interface converter; CPU debug socket, clock generators; DC / DC converters that generate supply voltages; current sensors; an indication and control system, consisting of LEDs and power on / off and reset buttons, into which, according to the utility model, a connector for connecting a Trusted Platform Module (TPM) is inserted; control and monitoring controller based on the domestic K1986 BE1QI controller manufactured by PPK Milandr JSC, connected to the central processor via the UART interface and controlling the operation of clock frequency generators, DC / DC converters, current sensors and an indication and control system.
